Abstract

L'invention concerne un dispositif interrupteur de touche, dans lequel la seconde partie came (24B) d'un second élément de liaison (4) est soutenu sur un élément en porte à faux (32) s'étendant à partir du second élément de liaison (4) sous la forme d'un porte-à-faux et cet élément en porte à faux (32) est sollicité par un ressort de torsion (33) dans la direction qui permet à la première partie came (24A) d'un premier élément de liaison (3) de venir en butée contre la seconde partie came (24B). Une face de came (25A) est formée sur la seconde partie came (24B), une face de came (25A) venant en butée contre des parties de contact linéaires et en pointillés de cette face de came (25A) de la seconde partie came (24B) selon un angle aigu dans une vue en plan et possédant une surface inclinée (60) est formée sur la première partie came (24A), et un espace vide (63) formé entre la partie de contact et le point fixe (64) du ressort de torsion (33), est prévu entre la face de came (25A) de la seconde partie de came (24B) et la surface inclinée (60).
